The Swiss Federal Tribunal rejected Valverde's request to overturn suspensions imposed by the Court of Arbitration for Sport and the Italian Olympic Committee (CONI).

The CAS banned the 30-year-old rider until January 2012 when it ruled in favor of the International Cycling Union and World Anti-Doping Agency in May. However, the court allowed Valverde to keep his 2009 Spanish Vuelta title and other victories gained before this year.

The two organizations asked CAS to extend Valverde's ban worldwide after he was first suspended by CONI from riding in Italy.

The Italian body pursued Valverde using evidence gathered in 2006 during the Operation Puerto case after Spanish authorities refused to prosecute him.
